Claims

[Scope of utility model registration request]

An operating lever is provided which is connected to an arm supporting the paper bail roller to move the paper bail roller toward and away from the platen and to turn on and off an autoloading switch. In the autoloading device for a printer that is biased in the direction of contacting the platen, a swinging body having a locking protrusion is attached to the operation lever, and the swinging body engages with the locking protrusion to load the paper bail. a first locking portion that maintains the roller in a normal position in contact with the platen; a second locking portion that engages with the locking protrusion to maintain the paper bail roller in a position that separates the paper bail roller from the platen; A fixed cam is provided in which a passage leading the locking protrusion to the first locking portion through an autoloading position where the autoloading switch is turned on is sequentially formed as an annular circulation path. Autoloading device for printers.
